i love chewing the ice to about the size of a marble, then letting it slip to the back of my throat. it takes a couple trys to get it to the right place without swallowing it, but when you do it feels really cool!

I usually chew it by letting it melt in my mouth a little, then just chewing but not all the way, just "hammering" the ice into smaller pieces, and then i get a piece about half an inch in diameter, and let it get stuck in my throat
